![]() ![]() The nodes are represented using icons that clearly depict the real-world equivalent."An automated teller machine or automatic teller machine" (ATM) (American, Australian, Singaporean, Indian, and Hiberno-English), also known as an automated banking machine (ABM) (Canadian English), cash machine, cashpoint, cashline or hole in the wall (British, South African, and Sri Lankan English), is an electronic telecommunications device that enables the clients of a financial institution to perform financial transactions without the need for a cashier, human clerk or bank teller. Connected to the server are the client nodes, where each node represents a terminal device such as workstation, laptop, scanner, or printer. The figure indicates that four or more servers are deployed at the system. The figure illustrates a node stereotyped as server that comprises of processors. The following figure shows the topology of a computer system that follows client/server architecture. ![]() Represent the topologies of client/server systems. Model devices in embedded systems that typically comprise of software-intensive collection of hardware. They are commonly comprised of nodes and dependencies, or associations between the nodes. Deployment DiagramĪ deployment diagram puts emphasis on the configuration of runtime processing nodes and their components that live on them. The file other.cpp has compilation dependency on otherheader.h. The file priority.cpp has compilation dependency on other.cpp. Two versions of myheader.h are shown, tracing from the recent version to its ancestor. It shows four source code files, namely, myheader.h, otherheader.h, priority.cpp, and other.cpp. The following figure shows a component diagram to model a system’s source code that is developed using C++. Representing schemas in modeling databases. Modeling configuration management of source code files while developing a system using an object-oriented programming language. Component DiagramĬomponent diagrams show the organization and dependencies among a group of components.Ĭonstructing systems through forward and reverse engineering. Object diagram is the static part of an interaction diagram.Įxample − The following figure shows an object diagram of a portion of the class diagram of the Banking System. It shows the instances of the things in a class diagram.

Classes in the systemīank, Branch, Account, Savings Account, Current Account, Loan, and Customer. The following figure shows the corresponding class diagram. A customer may also procure loans from the bank. However, a customer must not have more than one savings account or current account. A customer may open both a savings account and a current account. An account may be either a savings account or a current account. Each branch can have multiple accounts and loans. In each zone, one branch is designated as the zonal head office that supervises the other branches in that zone. Let us consider a simplified Banking System.Ī bank has many branches. It comprises of the classes, interfaces, and collaborations of a system and the relationships between them. Class DiagramĪ class diagram models the static view of a system. UML structural diagrams are categorized as follows: class diagram, object diagram, component diagram, and deployment diagram. ![]()
